WebMoving OBB vs. triangle intersection test. Requirements: to write a test function that, given a moving OBB (oriented bounding box) and a triangle, returns true whenever the OBB hits the triangle. The OBB is described by its half extents ( h1, h2, h3 ), principal axes ( a1, a2, a3) and center point C (cx,cy,cz). Webwhere a ray with origin P and direction d intersects a triangle defined by its vertices, A, B, and C at intersection point Q. The square region diagrammatically surrounding triangle ABC represents the supporting plane of the triangle, i.e., the plane that the triangle lies on. To perform ray-triangle intersection, we must perform two steps: 1.

WebJun 4, 2024 · The intersection line is the line made by the intersection of the two planes. Each triangle lies in a plane. There are three cases: the planes are parallel and do not intersect. The triangles obviously do not intersect. the planes are the same plane. The triangles might meet or might not. the planes are two different planes that meet at a line. WebA Fast Triangle-Triangle Intersection Test Tomas M ¨ oller Abstract This paper presents a method, along with some optimizations, for comput-ing whether or not two triangles intersect. The code, which is shown to be fast, can be used in, for exam ple, collision detection algorithms. 1 Introduction minimalist upright book shelves
